Cavidine protects against asthma in neonatal asthmatic mice model by attenuating PI3Ks/NF-κB signaling pathway
Abstract
Purpose: To evaluate the protective effect of cavidine against asthma in neonatal mice.
Methods: Neonatal mice were treated with cavidine at doses of 5 and 10 mg/kg, po, 2 h prior to asthma induction with ovalbumin (OVA) on the 1st and 14th days of the treatment protocol. The anti-asthma activity of cavidine was evaluated by determining the number of inflammatory cells and cytokine levels in broncho-alveolar lavage fluid (BALF) and OVA-specific IgE and TGF-β 1 in the serum of OVAsensitized mice. The levels of NF-ƙB and PI3K protein expression were determined in the lung tissues of OVA-sensitized mice.
Results: Cavidine attenuated the number of inflammatory cells and cytokines in BALF of OVAsensitized mice. The levels of OVA-specific IgE and TGF-β 1 decreased significantly in cavidine-treated groups, when compared to asthmatic group of mice, while NF-ƙB was significantly downregulated (p < 0.01). The altered expression of PI3K signaling protein was attenuated in the lung tissues of cavidinetreated mice sensitized with OVA.
Conclusion: These results reveal that the anti-asthma effect of cavidine in OVA-induced asthmatic neonatal mice occurs via reduction of inflammation and immune responsive cells linked to PI3Ks/ NF-κB signaling pathway in lung tissues. These findings suggest that cavidine may be clinically suitable for the management of asthma.
